Alex writes from Middlesbrough: "Found this odd homemade looking synth on eBay. With daisywheel printed names for all the knobs, this looks like a bit of a shambles, and therefore intruiguing. Weird... What is this?" It's a brilliant-looking design, with three octaves of toy keyboard, some kind of matrix/button panel, what look like crossfader sliders for the filters, and one of those big vernier dials from a Synthi. It has 'Quasar' written on the back, so it's possible this is a DUY Quasar, a ludicrously rare Spanish-made synth with a built in sequencer. But that seems unlikely. Currently just £53 - let me know if you buy it!
